Matt Smith, the current (and youngest) actor to star as the Doctor in BBC's Doctor Who, recently took to the stage in Los Angeles while dressed as Batman for a play called Gotham Autopsy, part of the 24 Hour Plays that were inspired by Scott McCloud's 24 Hour Comics (!!!) and are performed but once and never more. The Telegraph described the scene, which sadly none of us shall ever see again:

At the start of his play – called Gotham Autopsy – Smith was covered in a sheet in a mortuary before he came to life as a confused Batman. Comedian and Don't Mess With Zohan star Nick Swardson starred as Robin. Also in his play were Kick Ass star Lyndsy Fonseca and fellow Brit Saffron Burrows. Half-way through the 20 minute skit Smith dropped his fake American accent and became a cockney (Brit) to huge laughs from the audience.
